Smartphones have reached a point where they no longer offer the big leaps in innovation they once did.

Steve Wozniak, who co-founded Apple with Steve Jobs 41 years ago, has explained why the iPhone
X will be the first of the company’s smartphones he won’t be upgrading to on day one.The 67-year-old said he was not convinced by the new features the devices offers and that he was content to stick with his iPhone 8 for the time being.

  Mr Wozniak told CNBC:

 “I am just worried about what it provides me. I'd rather wait and watch that one. I'm happy with my iPhone 8, which is the same as the iPhone 7, which is the same as the iPhone 6, to me. I think I will watch other people in this case.

“For some reason, the iPhone X is going to be the first iPhone I didn't — on day one — upgrade to. But my wife will, so I'll be close enough to see it.”

His comments come just days before the iPhone X becomes available for pre-order on Friday October 27.

Apple has been billing the X as a paradigm shift for smartphones, with Tim Cook describing it “as a product that will set the path for technology for the next decade”.

The flagship smartphone introduces a host of new features such as an edge-to-edge 5.8in 'super retina' display and a Face ID function that will allow users to unlock the phone by looking at it.

CNBC reports Mr Wozniak also expressed skepticism that new features such as Face ID would work the way they are supposed to.

Mr Wozniak founded Apple with Steve Jobs, who died in 2011, in 1976 after the pair bonded over a mutual love of electronics as teenagers growing up in Palo Alto, California.

He is credited with being engineering brains behind Apple’s early success, which was complemented by Jobs’s abilities as a product visionary and marketer.
